JSTOR is the largest digital repository of academic books, journals and articles in the world, predominantly used in third level institutions. We are extremely fortunate to have a subscription, and I would strongly urge you to use it as a jumping off point for research.
The login in details are as follows:

The homepage has a basic search box into which you can type keywords and concepts. Once you have your results, a filter section on the left hand side of the screen will allow you to filter these for specificity. You also have the option to carry out an "Advanced Search".
